Multigene Family for Sarcomeric Myosin Heavy Chain in Mouse and Human DNA: Localization on a Single Chromosome

Abstract
Cloned myosin H chain DNA probes from rats and humans were hybridized to restriction endonuclease digests of genomic DNA from somatic cell hybrids and their parental cells. The mouse myosin H chain genes detectable by this assay were located on chromosome 11, and 3 different human sarcomeric myosin H chain genes were mapped to the short arm of chromosome 17. A synteny between myosin H chain and 2 unrelated markers, thymidine kinase and galactokinase, was found to be preserved in the rodent and human genomes.
